Why does ValueType (apparently redundantly) override ToString?

[GeeLaw]

I was writing some code to detect if an instance has an overridden string? object.ToString(); and found that ValueType overrides it with a copied body (and they have the same IL code). That's easy to work around by testing both object.ToString and ValueType.ToString, but the question remains: Why does ValueType override it at all?

Keep in mind that types like object and ValueType are special and they might have weird behaviours enforced on them by the runtime or debugging stack, not sure if that's the case hhere though.
